› When downloading local LLMs, GGUF files give you a choice between quantization tags like Q4_K_M, Q6_K, and Q8_0, indicating how aggressively the weights are compressed.
› In short: Q4_K_M is the practical sweet spot for most systems, Q5_K_M and Q6_K match uncompressed output almost perfectly, and Q8_0 makes sense only when VRAM is not a constraint.
› To understand where these files fit in your offline stack, check out the local AI models overview.
› As of 17 October 2026Official GGUF builds for Bielik v3.0 are released by SpeakLeash on Hugging Face (organization speakleash) under the Apache 2.0 license, allowing commercial use.The 1.5B repository offers F16 and Q8_0; the 4.5B repository provides F16 and Q8_0; the 11B repository provides Q4_K_M, Q5_K_M, Q6_K, Q8_0, BF16, and F16.I ran all benchmarks on llama.cpp on Windows with CUDA (build 11194 from 26 September).
